# Clear the previously set instance warmup for a scaling policy
<a name="clearing-the-previously-set-instance-warmup"></a>

After enabling the default instance warmup, update any scaling policies that have still their own warmup time to clear the previously set value. Otherwise, it will override the default instance warmup.

You can update scaling policies using the console, AWS CLI, or AWS SDKs. This section covers the steps for the console. If you use the AWS CLI or AWS SDKs, make sure you preserve the existing policy configuration, but remove the `EstimatedInstanceWarmup` property. When you update an existing scaling policy, the policy will be replaced with what you specify when you programmatically call [PutScalingPolicy](https://docs.aws.amazon.com/autoscaling/ec2/APIReference/API_PutScalingPolicy.html). The original values are not kept.

**To clear the previously set instance warmup for a scaling policy (console)**

1. Open the Amazon EC2 console at [https://console.aws.amazon.com/ec2/](https://console.aws.amazon.com/ec2/), and choose **Auto Scaling Groups** from the navigation pane.

1. Select the check box next to the Auto Scaling group. 

   A split pane opens up in the bottom of the page.

1. On the **Automatic scaling** tab, in **Dynamic scaling policies**, choose the policy you're interested in, and then choose **Actions**, **Edit**.

1. For **Instance warmup**, clear the instance warmup value to use the default instance warmup value instead.

1. Choose **Update**.
